sndrBlock™ is a palm-sized device that unlocks the next level of content sharing and puts you, the sender, back in control.

We designed sndrBlock to work with the devices you already use. Do you have an iPad, Windows desktop, Mac laptop, and an Android phone? No problem, sndrBlock will work across all of these devices so you'll have all of your communications, shared files, contacts, notes, passwords, and more on all of your devices. We even have a command line version for you power users!

sndrBlock removes the burden of gargantuan file uploads and downloads when you’re near it - gone are the days of waiting for a huge file to upload before you can pack up your devices!

When you send a message or file, it will be first transferred to your sndrBlock as fast as your internal network allows. From there, the device will transmit it on your behalf.

Always looking at slow progress bars? That's because like most of the United States, upload speeds are horrible. Because of this, you're forced to wait around on the cloud. sndrBlock handles cloud uploads for your devices and, if you want, will automatically download files sent to you so they are waiting for you when you get back home or to the office.

A few of you asked us to test the sndrBlock caching approach vs. directly uploading to Dropbox. This test measures the time it takes to get a 1.6GB video off of this iPhone using a sndrBlock vs Dropbox. Each test is performed on the same iPhone, same network, and the same file. The Dropbox test was performed on a different day when our ISP upload speeds matched our paid internet tier.

Gone are the days of arbitrary file size limits. The sndr team has tested our platform up to 5TB to make sure you never have a problem sending a file due to it's size - no matter what device you're using.

Max file sizes based on our real world tests

When you're away from the sndrBlock, you can remotely command it to share files and send messages securely. This means you’re free to head out and you'll still have access to all of your files without having to store them in the cloud.

sndrBlock moonlights as a virtual hard drive, allowing you to remotely command and access local storage devices without having to store a single thing in the cloud until you need it.

The built in cache on the sndrBlock not enough for you? Plug in a fast external drive or drive array on the USB 3 port and it'll augment your cold storage automatically.

Pressing “Send” shouldn’t mean giving up control of your message and content. Control your content after you hit 'Send', we call this sndrLeash. sndrBlock's unique security empowers you to cryptographically revoke your recipient's access to your files and messages in real time or based on a set of rules that you sent.

With sndrBlock you control your messages and files. sndrBlock lets you recall or annihilate messages anytime, even years from now—even if they’ve been forwarded.

Security isn’t just an added on feature, it’s at the very core of our mission to revolutionize digital communication and content sharing. The best part is, our end to end crypto is seamless... unless you're a power user and want to manage keys yourself.

Unlike other services that claim you have control or security, sndr is built on technology that is end to end secure. That means that only you and the people you specify will ever see your content.

For those looking to leverage the power and accessibility of the cloud without forfeiting security or control of a local server, sndrBlock offers the perfect solution.

When you choose to stash or send your files, sndrBlock can store the bulk of your encrypted data in the cloud, worry free. You control how much content is cached in the cloud. You hold the wrapped keys to your stored data on your devices, and you decide who has access to your messages and files, and what they can do with it.

This is the world’s first secure hybrid cloud cache with seamless union between physical and cloud storage that gives you all of this power, control and security in a single platform.

By default, messages and content are individually encrypted before they leave your mobile or desktop devices and the keys are wrapped for your recipients so only you and the people you specify can decrypt this data.

The platform can either automatically handle the public key operations for you (and warn you if something fails to verify or authenticate) or you can choose to manage and pin your and your recipients keys - your choice.

Since the sndrBlock is local area device, messages and content transfer as fast as your internal network allows from your mobile and desktop devices. No more waiting around on horrible upload speeds to the cloud!

sndrBlock will automatically split your files and message into multiple blocks. This is where the real sndr magic begins.

Most of these blocks will be sent to the cloud in their encrypted and split state - if a bad actor or rogue employee gets in there all they will get is random binary data.

One of these blocks will remain locally on the sndrBlock (and synced with your other devices.) Without it, the other blocks will fail to decrypt. That means you'll always be in control of the messages

When your communication reaches your intended recipient, the sndr app will bring all the pieces back together and their devices perform the decryption process. The blocks of the file are a part of a stream cipher that allows us to optionally split them up and retain a pattern that is required for decryption.

Of course, you, the sender, are still in control - you can recall or delete it anytime you want and the keys will be revoked.

This unique approach allows the sndrBlock to offer secure simultaneous uploads (bulk ciphertext to the cloud) and downloads (peer to peer to negotiate wrapped keys and pattern) so your recipients can download the shared content at the speed of the cloud even though your internet connection may not have a fast upload speed. All the while you maintain local control.

The sndr platform combines the functions of local storage device and cloud storage, file sharing, and messaging all into one unified platform. You won’t have to waste time jumping between cloud storage apps, messaging apps, and email apps. You can do it all with one secure platform.

There is no monthly fee for the sndrBlock and the sndr platform will be free for many users. Heavy users of our secure stash and send platform will have the choice of in-app subscriptions and a-la-carte options for upgrading their available space.

The sndr app is free to download, and users do not need the sndrBlock to communicate with contacts or to enjoy the robust features the sndr platform provides.

Despite not needing sndrBlock to utilize the platform, sndrBlock amplifies the features of the platform to unprecedented heights, and also provides its own unique features.

This is not just another messaging app, cloud storage app, or network attached hard drive. This is what digital communications is supposed to be.

The great thing about making the switch is that it's seamless! sndrBlock and the sndr platform lets you plug in your existing email addresses, phone numbers, and social accounts so your friends and family can reach you without having to know another username. You can send encrypted messages to anyone in your contacts even if they don't have sndr and they can see that message with one click.**

Email contacts? Of course. Phone contacts? Yes. You can even send secure communications to your Twitter contacts with more integrations, including an anonymous mode, coming soon.

The platform powering the sndrBlock is built upon years of research in communication and content sharing efficiency and security. We combined all of the features that real people told us they wanted and needed in a single platform while finally giving everyone true privacy and security... and we're not done yet!

Yours. Truly!

**Although our platform gives the sender the choice to send encrypted messages to their contacts when they don't have sndr, this method of communication does not provide the same level of security that can be found when communicating within the sndr platform. Also recipients cannot reply to your message if they are outside of the sndr network. sndr is an "inform but allow override" secure system, it allows reasonable degradation in security once the user is informed and chooses to proceed.

Pro content creator - You know you're a pro when you want to send a message with enough photos, 4K videos, or other content that would fill up the average modern smartphone and don't have the time to wait around for the cloud!

The modern team - You watch all of that productivity go down the drain while your office is waiting to upload to the cloud or are frustrated when your network file server is impossibly slow while you're working remotely or sending files to clients.

The sndrBlock team and the whole sndr family has the audacious goals of removing the burden of slow upload speeds found in the United States, protecting against constant data breaches from threats inside cloud providers and unknown bad actors while giving back control to those that create, think, and share.

We designed sndrBlock to be a one-stop platform for all your digital communications—messaging, content sharing, document stashing, password storage, and security. But our vision is even larger than that - it includes you.

We need your input! We want you to let us know which channels of digital communication you want evolved into something better. With your input and involvement, sndrBlock can become the go-to platform for things like conversational commerce, retail sales, payment security, even secure web browsing.

Let us know what you'd like to see next out of sndr and sndrBlock and together we can revolutionize digital communications.

sndrBlock is the beginning of a revolution, and it truly starts with you.

We are currently on revision C of our hardware and our software has been under test for many months. Thanks to you, at the conclusion of this kickstarter we will shift to manufacturing our boards at scale.

The team at sndr has many other products in the works and we thank you for being a part of this first step!

The hardware

We designed a low power board (about the power required to charge an iPhone) to accommodate our fast network and fast storage needs. If you are interested in our development kits, please contact us!

Risks and challenges

Even though we have concluded our hardware development and our software has been under extensive beta testing for months, there are some manufacturing risks that may cause schedule impacts.

FCC Issues:

In order for us to deliver our platform to the general public we have to be approved by the Federal Communications Commission, and ensure we meet their rules and regulations. If they do not approve us this could delay our projected timeline. However we are confident that we've taken all the necessary steps to ensure we meet the FCC's regulations, and will be able to deliver our platform to you on time and with the level of quality we promised.

Parts Availability:

As a small company, we're not high on the priority list for parts suppliers in comparison to tech giants. We are in the same industry as tech giants like Apple, Microsoft, Google, etc. and therefore if one of those companies buy out our parts from our suppliers then it would cause a setback in our production. This has given us even more drive to speed up development of the sndrBlock and the sndr™ platform so we can continue our mission to provide easy, efficient, secure messaging and file sharing for everyone.
